I feel as if naming anything from the current season would only be becuase it's still fresh in my mind, even though the only thing from this most recent season I'd even consider naming off would be girls und panzar (tanks are rad).
Not sure which one I'd go with betwen yuruyuri 2 and fate/zero.
I guess I'd go with the yuris, as for the why, well Yuri yuri is an all around fun and charming show about cute lesbians, what more could you ask for?
Runner up being fate/zero. while it might have had a lackluster second season in the same year, fate/zero was a really well done action packed exiting anime.
